Instead of passing a GlobalObject everywhere, we will simply pass a VM, from which we can get everything we need: common names, the current realm, symbols, arguments, the heap, and a few other things. In some places we already don't actually need a global object and just do it for consistency - no more `auto& vm = global_object.vm();`! This will eventually automatically fix the "wrong realm" issue we have in some places where we (incorrectly) use the global object from the allocating object, e.g. in call() / construct() implementations. When only ever a VM is passed around, this issue can't happen :^) I've decided to split this change into a series of patches that should keep each commit down do a somewhat manageable size.
